Alright, so after a bit of playing today I discovered the Sol system was open again so went there. Checked out Venus first and it was a repeat of the Antorian Dreadnaught battle (no dialogue though). Then tried Mars and again the Soviet Zombies (of which I destroyed their ship). So I decided to be bold and fight Admiral Micari. I didn't expect to survive--but I did. In fact all I lost was my two main engineers. In return? A measly 2 tokens! Clearly there have been budget cuts at Star Command if Admiral Micari's capital ship only produces 2 tokens of scrap.
